A US-led coalition fighting jihadists resumed regular patrols in Kurdish-held areas of northeast Syria on Friday after earlier Turkish air strikes, an AFP correspondent and a Kurdish military source said.
Patrols were reduced following the Turkish strikes that began on November 20 in Kurdish-controlled areas of Syria and Iraq, in response to a deadly Istanbul bombing that Ankara blamed on Kurdish groups.
The Kurds denied responsibility.
Hundreds of American troops are in Syria as part of the fight against remnants of the Islamic State group.
